Vector Store API calls returning 504s, 503s, and generally being slow

Haha nah, I don’t work for OpenAI just another brokedev goblin reading through the thread
But honestly the fact deleting/recreating the vector store temporarily fixed it does make it sound like something state-related may’ve gotten corrupted or stuck internally rather than this being purely a client-side issue
And yeah, I get the frustration. ~300 files really shouldn’t be enough to make a vector store workflow feel fragile
